Abstract

Undoubtedly, one of the most stimulating concepts introduced into aromatic chemistry is the generalization from simple molecular orbital theory known as the Hiickel rule. 5 This requirement that aromatic stability in conjugated, planar, monocyclic polyenes is associated with those molecules having 4n+ 2~ electrons has been amply confirmed by Doering, 6 Dauben,'Dewars and
